One Chat for ChatGPT, Google Gemini, and Claude

I used to switch between different apps just to cọmpare answers from ChatGPT, Gemini, and Claude. With CAI, I can do it all in the same chat window and swap models instantly without losing the thread. It’s genuinely useful for brainstorming, rewriting, and double-checking info. Simple, fast, and it saves a ton of time. 5 stars.
